Abstract
Gastrointestinal stromal tumors (GISTs) are rare mesenchymal tumors of the digestive tract, accounting for approximately 1–2% of all gastrointestinal neoplasms. Their prognosis depends on several factors, including location, rupture status, tumor size and mitotic index, which together determine the risk classification and guide therapeutic management. We report the case of a 70-year-old male patient admitted for the management of a small bowel GIST at the Department of Visceral Surgery I at the Mohamed V Military Hospital in Rabat. The patient underwent complete surgical resection. Histopathological and immunohistochemical analysis confirmed a high-risk GIST measuring 10.5 cm, with a high mitotic index. Adjuvant therapy with targeted therapy (imatinib) was initiated due to the high risk of recurrence.
